I used to do this all of the time in B19 days back when the DLL name
changed with each release.  That's changed now.  It was quite a battle
to get it changed, too (cgf bows).

The problem in this scenario is that just about every structure has changed
now.  stat, FILE, passwd, etc.  Changing the name of the DLL will just cause
most executables to crash.
